Description

Technical Field

[0001] This invention relates to the technical field of particle collection, and in particular to a flexible filter-type biomimetic microparticle collector. Background Technology

[0002] Currently, some related technologies have been used for the collection and filtration of microparticles, but there are still many shortcomings, mainly in terms of filtration efficiency, adaptability, and equipment flexibility.

[0003] Existing microparticle collection devices typically employ traditional filters or filter cartridges for particle capture, such as using fixed filter cartridges to capture airborne microparticles. However, the filter cartridges in these devices are usually rigid structures, unable to adapt to shape changes in complex environments, especially in narrow, winding pipes or spaces. This results in poor flexibility and adaptability, leading to low filtration efficiency. Furthermore, most existing filter cartridge materials are single rigid substances, unable to adaptively adjust to environmental changes, easily causing fluctuations in filtration efficiency under different fluid conditions.

[0004] Another type of technology is based on biomimetic microparticle collection devices, which improve particle capture efficiency by simulating filtration mechanisms in nature. These devices enhance filtration performance through a combination of biomimetic structures and special materials, but currently most of them use rigid or semi-rigid materials, which still cannot achieve flexible adjustment in complex environments.

[0005] Therefore, existing microparticle collection devices still have significant limitations in terms of filtration efficiency, adaptability, and flexibility, and there is an urgent need for a new type of solution that can operate flexibly in complex environments and provide efficient filtration. Summary of the Invention

The lead screw is housed within the housing. The slider is fitted over the lead screw, and the lead screw and the slider are connected by a threaded transmission. The slider is fixedly connected to the flexible filter element mechanism. The drive motor drives the lead screw to rotate, thereby controlling the multiple flexible filter filaments to move into the housing for bundled storage or to move out of the housing to restore their radial arrangement.

[0008] In one embodiment, the flexible filter element mechanism further includes a positioning block with a through hole for the lead screw to pass through. Multiple flexible filter filaments are arranged around the periphery of the through hole on one side of the positioning block, and the opposite side of the positioning block is connected and fixed to the slider.

[0009] In one embodiment, the flexible filter filament includes an elastic rod and filaments; one end of the elastic rod is connected and fixed to the positioning block, and the other end of the elastic rod extends away from the central axis of the positioning block; two rows of filaments are respectively connected to both sides of the peripheral wall of the elastic rod, and an obtuse angle is formed between the two rows of filaments, with the obtuse angle pointing towards the center of the positioning block.

[0010] In one embodiment, the outer casing includes a base plate and a cylindrical wall connected to each other; the drive motor is provided on the outer wall of the base plate, the drive motor passes through the base plate and is connected to the lead screw, and a coupling is connected between the drive motor and the lead screw; the cylindrical wall surrounds the lead screw.

[0011] In one embodiment, a guide groove is provided on the inner peripheral wall of the cylinder wall, and the guide groove extends along the axial direction of the lead screw; a guide block is provided on the outer peripheral wall of the slider, and the guide block is slidably installed in the guide groove.

[0012] In one embodiment, a guide rod is provided inside the cylinder wall, the guide rod extends axially along the lead screw, one end of the guide rod is connected to the base plate, and the other end of the guide rod passes through the guide block.

[0013] In one embodiment, the guide block includes a first guide block and a second guide block, arranged in a cross shape, with multiple first guide blocks and multiple second guide blocks alternately arranged on the outer peripheral wall of the slider, and each of the multiple first guide blocks passing through the guide rod.

[0014] In one embodiment, the output shaft of the drive motor is fitted with a bearing, which is located between the base plate and the coupling.

[0015] The beneficial effects of this invention are as follows:

[0016] The flexible filter-type biomimetic microparticle collector of this invention has significant advantages in terms of flexibility, environmental adaptability, and collection capability.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] This invention provides a flexible filter-type biomimetic microparticle collector, the implementation of which is as follows: Figures 1 to 4 As shown, the device includes a flexible filter element mechanism 10 and a reciprocating drive mechanism 20. The flexible filter element mechanism 10 includes multiple flexible filter fibers 11 arranged radially. The reciprocating drive mechanism 20 includes a housing 21, a lead screw 22, a slider 23, and a drive motor 24. The lead screw 22 is housed inside the housing 21. The slider 23 is sleeved on the lead screw 22, and the lead screw 22 and the slider 23 are connected by a threaded transmission. The slider 23 is fixedly connected to the flexible filter element mechanism 10. The drive motor 24 is used to drive the lead screw 22 to rotate, thereby controlling the multiple flexible filter fibers 11 to move into the housing 21 for bundled storage or to control the multiple flexible filter fibers 11 to move out of the housing 21 and return to a radial arrangement.

[0027] Assuming that in the default state, all the flexible filter fibers 11 are stored inside the housing 21, if it is necessary to collect microparticles in a certain space, the drive motor 24 can be used to control the screw 22 to rotate, and the slider 23 can be used to move the flexible filter fibers 11 to the outside of the housing 21. Once the flexible filter fibers 11 have moved to the outside of the housing 21, they will automatically return to their initial radial shape to better adsorb microparticles in the space. At this time, the drive motor 24 can be used to control the screw 22 to reverse, and the slider 23 can be used to move the flexible filter fibers 11 to the inside of the housing 21 to collect microparticles.

[0028] In this process, the present invention essentially uses tube worms as biomimetic objects because tube worms have a strong ability to adapt to complex aquatic environments and can capture and retain suspended particles with a diameter of less than 3 μm, which is consistent with the characteristics of most microparticles / microbacteria with a diameter between 0.5-5 μm. Therefore, after biomimetic design, the present invention can obtain similar performance.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment of the flexible filter element mechanism 10 also includes a positioning block 12. The positioning block 12 is provided with a through hole 121 for the lead screw 22 to pass through. Multiple flexible filter wires 11 are arranged around the periphery of the through hole 121 on one side of the positioning block 12. The opposite side of the positioning block 12 is connected and fixed to the slider 23.

[0030] With this configuration, the perforation 121 on the positioning block 12 can provide a moving path for the lead screw 22, ensuring that the slider 23 can smoothly drive the positioning block 12 and multiple flexible filter wires 11 into or out of the housing 21.

[0031] like Figure 4 As shown, this embodiment provides a flexible filter filament 11 including an elastic rod 111 and filaments 112; one end of the elastic rod 111 is connected and fixed to the positioning block 12, and the other end of the elastic rod 111 extends away from the central axis of the positioning block 12; two rows of filaments 112 are respectively connected to both sides of the peripheral wall of the elastic rod 111, and an obtuse angle is formed between the two rows of filaments 112, with the obtuse angle pointing towards the center of the positioning block 12.

[0032] After adopting this setting, the filaments 112 will form a tendency to converge toward the center of the positioning block 12, so that when multiple flexible filter filaments 11 move into the housing 21, the filaments 112 can better collect microparticles into the housing 21.

[0033] like Figure 1 and Figure 2As shown, in this embodiment, the outer casing 21 includes a base plate 211 and a cylindrical wall 212 that are connected to each other; a drive motor 24 is provided on the outer wall of the base plate 211, the drive motor 24 passes through the base plate 211 and is connected to the lead screw 22, and a coupling 25 is connected between the drive motor 24 and the lead screw 22; the cylindrical wall 212 surrounds the lead screw 22.

[0034] With this configuration, the base plate 211 can be used to install and fix the drive motor 24, and the cylinder wall 212 can be used to enclose the lead screw 22.

[0035] like Figures 1 to 3 As shown, in this embodiment, a guide groove 213 is provided on the inner peripheral wall of the cylinder wall 212, and the guide groove 213 extends along the axial direction of the lead screw 22; a guide block 26 is provided on the outer peripheral wall of the slider 23, and the guide block 26 is slidably installed in the guide groove 213.

[0036] With this configuration, the cooperation between the guide groove 213 and the guide block 26 will limit the slider 23, ensuring that after the lead screw 22 rotates, the lead screw 22 can drive the slider 23 to move back and forth.

[0037] like Figures 1 to 3 As shown, in this embodiment, a guide rod 27 is provided inside the cylinder wall 212. The guide rod 27 extends along the axial direction of the lead screw 22. One end of the guide rod 27 is connected to the bottom plate 211, and the other end of the guide rod 27 passes through the guide block 26.

[0038] After adopting this setting, the guide rod 27 can be used to further limit the movement trajectory of the guide block 26, thereby making the movement of the guide block 26 more stable and smooth. The number of guide blocks 26 and guide rods 27 is not unique. For example, in this embodiment, the guide block 26 is set to include a first guide block 261 and a second guide block 262, arranged in a cross shape. Multiple first guide blocks 261 and multiple second guide blocks 262 are alternately arranged on the outer peripheral wall of the slider 23, and multiple first guide blocks 261 are all passed through guide rods 27, thereby further improving the movement stability of the guide block 26.

[0039] like Figure 2 As shown, in this embodiment, the output shaft of the drive motor 24 is fitted with a bearing 28, which is located between the base plate 211 and the coupling 25.

[0040] With this configuration, the rotational smoothness of the output shaft of the drive motor 24 can be improved by utilizing the bearing 28.

[0041] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
